Salem Hyde just isn't like other kids. For one thing, she's stubborn, independent, and impulsive. For another, she's a witch. Good thing she's been assigned an animal companion, Lord Percival J. Whamsford III. This over-anxious cat doesn't like Salem calling him "Whammy," and Salem doesn't like listening to his long-winded explanations as to why she shouldn't do something, like enter the class spelling bee, go to birthday parties, or bake cookies!
